PAPER-CUTTING MACHINE.

To all-whom it may concern:

Be it known that I, V ew; L. Florian, a

citizen of the United States of America, re-

siding in the city of Baltimore, State of Maryland, have invented certain ,new and useful Improvements in Paper-Cutting Ma-' ficiently, The apparatus offered for this purpose, having but one shearing b1ade,will trim one side only at each operation, and the manually operated cuttingor trimming unachines that have beenin'use in the past will cut but few thicknesses or sheetspat one time. The. single blade cutting machines cause thepaper to buckle-land ,gather toward the blades, when being used to cut more than}, two or three thicknesses, giving the paper or :print, when. cut,-an,uneven edge ormagin. In photographic work, itfis important that the trimmed edgesbe parallel. The single blade cutters will \not give the desired result. i

The obj ect. of this invention is ;to provide a machine that will overcome these inefficiencies, that is, one which will handle a large number of prints or sheets at-eaclr operation and cut the edges parallel and at right angles without difliculty so .that no skill in: operation is necessary. The structure also has the advantages that it .is cheap, simple and durable andcanibe maintained without expense.

In its preferred form .the @paper cutter consists of two cutting or shearing blades, held in parallel relation and adapted to be adjusted in parallel relation toward and from each other; ,a cutting-board with graduations to determine the positions of the cutting blades; adjustable stops or guides carried by the cutting board, and means for operating the blades together with a shearing motion in relation to and in cooperation with the cutting-board.

In the accompanying drawing I have illus- Specification of Letters Patent.

trated a paper cutter embodying the features of rnyinventlon in the preferred form.

In the drawings-- E gu V1 i a sid elevatio .of the c mplete pap cu g machine, show ng t blades in full lines in inoperative position and in fine dotted .lines inoperative position.

Fig 2 is a plan view of the completedevlce.

Fig. 3 is an end elevation ,illustratingseveral thicknesses of paper or photographic prints ready to be cut ortrimmedQ I M Referring to the drawings by numerals, I have illustrated a photographic ,print cutting. device or paper cutting ,machine which consists of frame members 1 and 2 supported or held in rigid relationieach (with the other by stiffeningior end ,fra ne bars, 3

and 4:. The frame members 1 and 2, carry shafts 6 and 7, which are ,held (in place ;by any suitable means, as cotter ,pins, 8 and 9 respectively. Pivotally nounted on each of these shafts, 6 and 7, aretwo pairspfiextension ,or swinging arms, 10 and 11 re spectively which nove inan arc of about 90 degrees about the respective shafts,:6 and T, as shown'in full-and in dotted lines inFig. 1 of the drawing. These arms each have bearings at 112 and {13;bY'FWhICh they engage shafts G and 7,;thesha-ftseach in turn have bearings, ll. and1l5 respectively in theframe em s, 1 an Q- A .sh w ni e dra g"P f Q1 I" refe en fl ing-ma am F 2, it will be seenthatthe f-ralne members, 1

and 2,;are .eachislotted at 516 and 17 respectively as aguide forthe arms, 10 andll. 'th pp r o e d :o th ingi arms, 10 and ll, ;ar.e bearings, 181an'd 19,190].-

the blade, supporting shafts or and 21, WlllCll may he held, as shown, in their proper positions by .cotter pins, 9. The

shafts, 20 and v21,qact as supports for-l the blade rry g memb r .2 ;d;23 wh ar adjnstableenan i n sliding. relatio to tion with the gage and stop, 88.

The blades may be held in place or attached to the blade carrying members by means of screws or rivets, 28, or the blades and their supporting arms may be made integral or all in one piece.

In this lnstance a lever, 29, as shown, is used with a handle, 30. This lever is connected to the shafts, 7 and 21, by means of i the bearings, 31 and 32 respectively, and may be moved to any position on the shafts as to accommodate itself to and not interfere with the adjustment of the shearing members, 22 and 23.

The distances between centers of the shafts, 621 and 721, being the same, the arcs scribed by the extension arms, 10 and 11, are identical enabling the knife edges, 33 and 34, to constantly assume'a horizontal position throughout the cutting stroke. This is a very important feature as it is essential that the full length of the knife edges, 33 and 34, should touch and come in contact with the top of the cutting board, 35, and of the material being cut to insure the cutting of the last sheet or thickness of paper lying next to the cutting board, and to prevent displacement of the sheets. The blades, 26 and 27, by means of the shafts; and swinging arms engage the paper and move in the part of the arc which give them the necessary shearing motion so desired in all paper cutting machines.

The cutting board, 35, is secured to the frame members, 1 and 2. To assist in determining the width of the print or paper to be cut the board may be scored as shown at 37 to any desired number of graduations.

A gage and stop, shown at 38, and having a tongue, 39, inserted in an opening, 40, to hold it in position may be used to fix and indicate the spacing of the blades, by having any number of these gages of various widths and keeping the inside surfaces of the blades in sliding contact with the sides, 41 and A2 of the gage when the blades are in operation, and prevent the blade members from creeping on the shafts and cutting or trimming either too little or to much of the margin of the photographic prints. Another stop, 43, may be used in conjunc- This ad justable stop, 4:3, is held in place by the nut, 44:, in the slot, 15, in the cutting board, 35. The machine may be permanently fastened to a table or the like by means of screws or bolts being inserted in the holes, 46 in the end frame bars, 3, and 4.

In the operation of the machine the prints,

or sheets, are placed upon the cutting-board in multiple thicknesses with the edges in contact with the abutment or stop, 43, and the gage, 38. As previously explained the blades, gages and stops are adjusted accord ing to the graduations to determine the cut, the knives or blades, 27, are then made to move down by pressure on the handle operating with a shearing motion to cut opposite edges of paper or prints, as shown in fine dotted lines in Fig. 3, and then moved back to normal position When the operation is complete for the trimming of the two margins or borders. After the complete supply of prints have been trimmed or out along the end edges the machine is then readjusted and the prints are trimmed along their side edges. 1

Having thus described a paper or photographic print cutting machine, embodying my invention specifically in order that it may be made and used by those skilled in the art, I would have it understood that I do not intend to limit my invention to the details thus described.

lVhat I claim and desire to secure by Letters Patent is:

1. In a paper cutting machine, a frame, a cutting board thereon, four arms pivoted adjacent the horizontal plane of the cutting board, to swing above the cutting board, two cutting blades pivotally connected to said arms to swing toward and from the cutting board in parallel relation thereto, and an actuating lever connected to the swinging members, and projecting upward therefrom.

2. In a paper cutting machine, a frame, a cutting board thereon, arms pivoted adjacent the horizontal plane of the cutting board, to swing above the cutting board, two cutting blades pivotally connected to said arms to swing toward and from the cutting board in parallel relation thereto, and an actuating lever connected to the swinging members and projecting upward therefrom, the cutters being adjustable toward and from each other in parallel relation, gages on the cutting board at right angles to each other, one of said gages being adjustable at right angles to the knives to determine the margin to be cut.
